| Abstract | The structural gene for the type 24 M protein of group A streptococci has been cloned and expressed in Escherichia coli. The complete nucleotide sequence of the gene and the 3' and 5' flanking regions was determined. The sequence includes an open reading frame of 1,617 base pairs encoding a pre-M24 protein of 539 amino acids and a predicted Mr of 58,738. The structural gene contains two distinct tandemly reiterated elements. The first repeated element consists of 5.3 units, and the second contains 2.7 units. Each element shows little variation of the basic 35-amino-acid unit. Comparison of the sequence of the M24 protein with the sequence of the M6 protein (S. K. Hollingshead, V. A. Fischetti, and J. R. Scott, J. Biol. Chem. 261:1677-1686, 1986) indicates that these molecules have are conserved except in the regions coding for the antigenic (type specific) determinant and they have three regions of homology within the structural genes: 38 of 42 amino acids within the amino terminal signal sequence, the second repeated element of the M24 protein is found in the M6 molecule at the same position in the protein, and the carboxy terminal 164 amino acids, including a membrane anchor sequence, are conserved in both proteins. In addition, the sequences flanking the two genes are strongly conserved. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
